66629 divided by 35 
The aim is to understand the frequency of 35 in 66629.

Going ahead to step 1:
35 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 35

On to step 2:
35 can be fit into 66 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 35 from 66 to get 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 35

Moving on to step 3:
35 goes into 316 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 315 from 316 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 35

Step 4:
35 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we take 0 away from 12, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 35

On to step 5:
The number 35 fits into 129 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 1903.0
If we subtract 105 from 129, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 6:
35 can be fit into 240 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 1903.6
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
When dividing 300 by 35, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 1903.68
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 35 fits into 200 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1903.685
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
35 goes into 250 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1903.6857
The remainder is 5 after subtracting 245 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
If we divide 50 by 35, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1903.68571
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 1903.685714
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
100 divided by 35 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 1903.6857142
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
When dividing 300 by 35, we get 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 1903.68571428
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 1903.68571428 with a remainder of 2e-08.
